I fell in love with this smartphone at first sight - it is thin, with a large bright screen, a separate camera button ... In general, everything is the way I like it. I decided to buy this miracle for my use. In principle, I am not disappointed, because in every gadget there are pros and cons, there are no perfect ones. First of all, I would like to note the quality of the screen. It is beyond praise - the brightness is excellent, the color rendition is excellent, the viewing angles are maximum. But there is a fly in the ointment - an oleophobic coating. No, it seems to be even present, but of such a terrible quality that you cannot look without tears. He collects prints instantly, and erasing them turns into a whole story. All the same, the screen looks kind of stained. Although maybe I need to wash my hands more often? I don’t know, but there were no such problems with other smartphones. The sound is loud enough, does not wheeze or squeak. But even here Sony found something to distinguish themselves - just put the smartphone screen up and you can safely skip the call. In this case, only the cover saves, which at least slightly lifts the smartphone. Not without problems with calls. The fact is that sometimes people tell me that they hear me quietly, like from a pipe ... For a long time I could not understand what was the matter, because after the reboot everything became normal. In general, in order to rid the gadget of this ailment, you just need to turn off the "Ok, Google" recognition from any application, it is located somewhere in the Google Now settings. It is strange, however, to have a smartphone with an operating system from Google and not enjoy all the benefits. Maybe they'll fix it with the next firmware. By the way, this is not my first smartphone that has problems due to Google services. That's all with critical remarks, with the rest you can live peacefully. Love the dedicated camera button! It's just insanely convenient, but you get used to it very quickly. Then it is very difficult to readjust to photographing from a button on the screen. In terms of photo quality, I am completely satisfied with the Xperia C4. I didn't expect something supernatural from the camera, but in comparison with the Asus Zenfone 2 Sony takes pictures just amazingly. There is, however, a small nuance in this - with the super auto mode, the photos are soapy, but if you just switch to manual mode and do not change any settings, then everything becomes fine. It's strange of course :) I decided somehow to use the front camera with a flash ... And why did no one warn me that I would go blind for a while? :) I didn't use it anymore, experiments were enough for a lifetime. I can not understand Sony's policy in only one thing - the capacity of the battery. When other manufacturers put a 3000mAh battery with exactly the same specifications, Sony sets a 2500mAh battery. Where is the logic? The vaunted Stamina does not suit me, since I pay money to always receive all notifications and use the Internet, and not turn off all this in the device. If you do not play the smartphone, then the battery lasts for about 3-4 hours of the screen on. If you use a smartphone to its fullest, then the maximum is 1.5 hours, and sometimes even less. And yes, be prepared for it to warm up. It gets very hot. In my opinion, he can even fry eggs :) In general, if you are ready for all the disadvantages, the smartphone is a pleasure. It is powerful, beautiful, with a good camera, great display, well-built, waiting for an update to Android 6.0. In spite of everything, I am completely satisfied with the purchase, as I knew what to prepare for.
Sony Xperia C4 Dual is one of the new products of 2015, which offers users excellent technical parameters, a large display, a selfie camera and has two SIM card slots, which will allow you not to prejudice yourself when choosing the best tariff from operators for calls and the Internet. If you are looking for a multimedia device that can delight you every day in all aspects, then this model will suit you best. Well, let's start the Sony Xperia C4 Dual review, of course, with the design.
In our opinion, the model turned out to be quite beautiful - the design of OmniBalance shows the features of other models of the latest generation line, but the smartphone looks original. Small frames around the display, which is shifted slightly downward, and the top of the bezel is accentuated by the front camera, rounded side edges and a back cover. The physical dimensions of the phone are 150.3 x 77.4 x 7.9 mm and the weight is 147 grams.
These are already average dimensions for today, but it is worth considering that the phone has a 5.5-inch screen, so you get more, while the ergonomics and usability of the device remain at a very high level. By the way, the matrix has a Full HD resolution (1920 x 1080 pixels) and shows itself very well in any conditions, with accurate color reproduction, saturation and a large margin of brightness.
It is impossible not to say about the basis of the hardware of the Sony Xperia C4 Dual E5333, because here the Japanese used a good Mediatek MT6752 chipset with a 64-bit 6-core 1.7 GHz processor, a Mali760 MP2 video accelerator, and 2 GB of RAM complements them. This is quite enough to provide excellent performance in any task, be it modern games, applications or other content. The internal memory in the phone is 16 GB, of which about 11 GB is available for the user, but you can always expand it using microSD cards up to 128 GB. The battery with a capacity of 2600 mAh is enough for a full day of work in active mode or about two days with average use, which is a very good result with such parameters. It is the two-SIM version that has the model number E5333 and works in 2G, 3G and 4G LTE networks.
Thanks to the main 13-megapixel camera, you can take very good pictures in good lighting conditions, but in insufficient light, the camera shoots well too, but the color rendition is a little lame. If you love taking selfies, you will definitely love the 5MP front camera. In addition, it has wide-angle optics and a soft LED flash that illuminates the entire frame. As for a front camera, this camera works out with a bang.
Examples of photo quality
An example in a photo on a selfie camera
Sony Xperia C4 video:
Do you like taking selfies? Sony has great news for you: the bright and cute Xperia C4 smartphones take great pictures with their 5MP wide-angle front camera. In addition, the smartphone has an excellent rear camera, a powerful processor, a large bright screen and impressively clear sound.
Your self-portraits will get many likes!
The front camera of the Xperia C4 and C4 Dual is based on a 5MP sensor and a 25mm wide-angle lens. All friendly company of friends will fit into the frame! And a single selfie will turn out to be original and high-quality even in the dark - the front LED flash will gently illuminate your face during a night walk or a party.
Film yourself and the world around you
Not only the front camera, but also the main camera of the C4 smartphone deserves attention: it has a resolution of 13 megapixels and a light-sensitive lens, so it takes clear and bright pictures even in dim lighting. The camera supports HDR shooting, SteadyShot video stabilization technology and Intelligent Auto that instantly judges conditions and selects the best shooting settings.
Have fun and create masterpieces with Sony apps
C4 series smartphones offer tons of possibilities for creative processing of your photos: filters and artistic effects, apps for retouching selfies, creating fun photo collages and much more. You can always download new applications without leaving the shooting mode.
